Re: dump among different versions of postgreSQL

I've successfully dumped and restored a database containing large objects with 7.3.3 and previous versions. I've used the 'tar' archive format something like this:

% pg_dump -F t -b dbwithlos | gzip > dump.tar.gz
% zcat dump.tar.gz | pg_restore -d restoredbwithlos
